CM4012bg – 4MHz Internal Oscillator Ultra Low Power (1μ A@4MHz@1V)

Clock Management

This macro-cell is a general purpose, ultra low power internal oscillator core designed for LFoundry 0.15μm LF150 CMOS technology STD (Standard) and LP (Low Power) process.

The circuit has internal level shifting and start-up circuits. A 4-bit digital bus allows frequency calibration against process variations. It also includes an internal current bias.

The core is easily retargeted to any other CMOS technology due to its MOSFET-only oscillator architecture.
